Multiple proxy:errors in /var/log/apache2/error.log
cn flag

I am not sure where these warnings are for/concerning. Should I be worried about them or just ignore them as people are trying to connect to my server? Proxy Mod is already enabled, however I am less concerned about this and more the fact my apache instance is showing random ip's and web addresses that are trying to be proxied :?

No option to choose X11 on logging into Ubuntu 21.10
cn flag

I recently bought a Dell Precision 7550 notebook. It came with Ubuntu 18.04 installed, but I wiped it and installed 21.10. On log in, I don't have the gear menu to switch between X11 and Wayland and Ubuntu defaults to Wayland on log in. As far as I tell, it runs Wayland until I open something (like Steam) that wants to use my NVIDIA card over my integrated card and then it switches to X11 for as long as ...

How can I shutdown my laptop in one mouse click (or maybe two mouse clicks) from the unity launcher?

I'm n00b running Xubuntu Core on a Virtual Machine.
I connect to it by xRDP (version 4 I think) and tried VNC but got the same problem
So I don't think it has to do with xRDP or VNC, but something else.

Here is the problem:
Every time I disconnect accidentally, on purpose, or by a timeout and try to login again.
I fill in my username & password and get stuck in this Login-Screen

The Stunning Power of Questions

Much of an executive’s workday is spent asking others for information—requesting status updates from a team leader, for example, or questioning a counterpart in a tense negotiation. Yet unlike professionals such as litigators, journalists, and doctors, who are taught how to ask questions as an essential part of their training, few executives think of questioning as a skill that can be honed—or consider how their own answers to questions could make conversations more productive.

That’s a missed opportunity. Questioning is a uniquely powerful tool for unlocking value in organizations: It spurs learning and the exchange of ideas, it fuels innovation and performance improvement, it builds rapport and trust among team members. And it can mitigate business risk by uncovering unforeseen pitfalls and hazards.

For some people, questioning comes easily. Their natural inquisitiveness, emotional intelligence, and ability to read people put the ideal question on the tip of their tongue. But most of us don’t ask enough questions, nor do we pose our inquiries in an optimal way.

The good news is that by asking questions, we naturally improve our emotional intelligence, which in turn makes us better questioners—a virtuous cycle. In this article, we draw on insights from behavioral science research to explore how the way we frame questions and choose to answer our counterparts can influence the outcome of conversations. We offer guidance for choosing the best type, tone, sequence, and framing of questions and for deciding what and how much information to share to reap the most benefit from our interactions, not just for ourselves but for our organizations.
